Internal & External Thread BS EN 148-1:1999 (Rd 40 x 1/7) · 模型 231382
A request from the Question section to make this thread. This is a European standard for respirators and gas masks. Maybe you'll find some use for this in making an adapter for a gas mask? This model is based on dimensions shown in Table 1 - Thread Limits from BS EN 148-1:1999. It says the European standard EN 148-1:1999 has the status of a British Standard. The thread designation is Rd 40 x 1/7 Internal and external threads are included. Original question can be found here: https://grabcad.com/questions/corona-need-help-for-german-police Original poster printed the model and it does fit correctly.
